To investigate the related factors that could cause infection after burn plastic surgery, and to put forward the corresponding treatment measures and recommendations.

Total of 88 patients with infection symptoms were collected randomly from January 2013 to December 2015. There were 88 patients without infection were selected during this period as control group. The influencing factors of infection after burn plastic surgery and the countermeasures were analyzed by Univariate analysis and multivariate Logistic regression analysis.

Univariate analysis showed that there were no signs of scarring, with or without residual wounds, the number of antimicrobial agents and the time of operation were related to postoperative infection of burns. According to the results of multivariate Logistic regression analysis (OR = 2.812, P = 0.026), scar wounds (OR = 3.148, P = 0.011), residual wounds (OR = 2.711, P = 0.030) and operation time ≥ 200 (OR = 2.883, P = 0.019) were all the risk factors of postoperative infection, respectively. The pathogen test showed 35.23% and 64.77% of Gram-positive and negative cocci infection. The main pathogens were Pseudomonas aeruginosa, Staphylococcus aureus and Escherichia coli.

Hospitals should avoid the use of multiple types of antibiotics at the same time, shorten the operation time appropriately and take measures to eliminate scar wrinkles and residual wounds in order to inhibit the infection after burn surgery.
